Webpack4 を使って webpack-dev-server のベーシック設定

Last updated at Posted at 2018-05-17

経緯

本番用には webpack-cli でビルドして、開発環境では webpack-dev-server というあるあるなビルドの仕組みを作った時に、 webpack-dev-server では dist ができずにちょっと悩んだので、簡単に記載しました。

webpack4 もまだあまり試していなかったので、ついでにと思ってやってみました。

code

package.json
{
  "name": "sample",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "rm -rf dist && NODE_ENV=development webpack-dev-server --open --config ./webpack.config.js --hot --inline",
    "build": "rm -rf dist && NODE_ENV=production  webpack --mode production"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "babel-core": "^6.26.3",
    "babel-loader": "^7.1.4",
    "babel-preset-env": "^1.7.0",
    "copy-webpack-plugin": "^4.5.1",
    "webpack": "^4.8.3",
    "webpack-cli": "^2.1.3",
    "webpack-dev-server": "^3.1.4",
    "write-file-webpack-plugin": "^4.3.1"
  }
}

webpack.config.js
const path              = require('path');
const webpack           = require('webpack');
const WriteFilePlugin   = require('write-file-webpack-plugin');
const CopyWebpackPlugin = require('copy-webpack-plugin');

const NODE_ENV = process.env.NODE_ENV;


module.exports = {
	context: path.resolve( __dirname, './src'),

	mode : NODE_ENV || 'production',

	devServer: {
		port: 3000,
		contentBase: path.resolve( __dirname , './dist' )
	},

	entry: {
		bundle : [ './js/index.js' ]
	},

	output: {
		filename : '[name].js',
		path: path.resolve( __dirname , './dist/js' )
	},

	module: {
		rules: [
			{
				test: /\.jsx?$/,
				exclude: /node_modules/,
				use: [
					{
						loader: 'babel-loader',
						options: { presets: ['env'] }
					}
				]
			}
		]
	},

	resolve: {
		extensions: ['.js', '.jsx'],
	},

	plugins: [
		new WriteFilePlugin(),
		new CopyWebpackPlugin( [
			{ from: '*.html', to: path.resolve( __dirname , './dist' ) }
		]),
		new webpack.DefinePlugin({
			'NODE_ENV': JSON.stringify( NODE_ENV ),
		})
	]
}

今後

sass もコンパイルする設定を足したいので、今度余裕がある時にでも。
